BELL MECHANISM.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed July 9, 1907. Serial No. 382,936.

To all whom it may concern:

Be it known that I, WILLIAM R. MOORE, a citizen of the United States of America, re siding at East Orange, county of Essex, and State of New J ersey, have invented certain new and. useful Improvements in Bell Mechanism, of which the following is a full, clear, and exact description.

My invention relates to improvements in bell mechanism.

The main object is to provide a simple and reliable mechanism which can be made cheaply and readily installed.

Another object is to reduce to a minimum the power necessary to operate the mechan- 1sm.

The accompanying single sheet of drawings illustrates the proposed form of the invention which will be more thoroughly understood from the following specification.

Figure 1 is a front view of mechanism of my invention, the gong on bell being removed. Fig. 2 is a horizontal sectional view looking up from below, the gong being present. Fig. 3 is a view similar to Fig. 1, the striking mechanism being removed and part of it suggested in dotted outline. Fig. 4 is a front view of the hammer and pallet member removed. Fig. 5 is a bottom view of the same.

The base 1 is suitably mounted or secured to a support 2, on the opposite side of which is the push-button 3. This method of operation is illustrated as convenient and desirable, but not essential to the invention.

The central post 4. carries the bell or gong 5. At the top edge of the base is mounted the hammer having the two spring arms 6, 6, with usual striking heads. The pallet 7, is secured to the hammer and the two pivoted on the horizontal shaft 8, so that the hammer arms hang down evenly and out of contact with the gong.

The teeth of the escapement wheel 9 are cut so that the wheel is not reversible and it rotates only in the direction of the arrow.

Secured to wheel 9 is pinion 10, and the two are mounted on shaft or base 11 and driven by gear 12, which is mounted on axis 13. Arm 14 is also pivoted on axis 13 and carries pawl 15 which is pressed by spring 16 into engagement with the teeth of gear 12.

Normally spring 17 presses arm 14: against the flange of base 1, so that no pressure is exerted against the teeth of the escapement wheel and the pallet and the hammer arms hang down freely. hen the button 3 is pushed in, rod 18 swings lever 19 and thusbutton and it requires no winding or rewindlhe special advantages of the particular mechanism shown will be appreciated by those acquainted with the art.

WVhat I claim is l.- In a bell mechanism, a base having a flange, a hammer, a pallet connected thereto, a train of gears for oscillating the pallet and hammer, an arm and pawl for rotating said train in one direction, a spring normally holding said arm against the base flange and means for moving the pawl arm away from said flange.

2. In a bell mechanism, a base and gong, a hammer and pallet having a common axis, an escapement wheel engaging said pallet, a pinion on the axis with said wheel, a gear meshing with said pinion, a swinging arm on the axis with said gear, a spring-pressed pawl carried by said arm and engaging the teeth of said gear, a two armed lever having one arm connected to said pawl arm and means for operating the other arm of said lever.

3. In a bell mechanism, a base, three pivot shafts and a post carried thereby, a pawl arm and gear mounted on one shaft, the arm be ing beneath the gear, a pawl pivoted o said arm and engaging said gear, a pinion and escapement wheel mounted on the second shaft, the pinion being beneath the wheel and meshing with said gear, a hammer and pallet mounted on the third shaft, the pallet being beneath the hammer and connecting with the escapement wheel, and a gong or bell mounted on the post in front of said parts.
